CONTAINER SUPPORTING APPARATUS FOR CONTAINER SHIP This invention relates to a container supporting apparatus for container ship, more particularly to a removable supporting apparatus for stacking more than seven containers.

The container ship is provided with container guides located in the container hold, the guides forming the four corners of each of a series of container cells into which containers can be loaded and stacked in superimposed relation. It is not permitted to stack more than six containers in each cell. That is the bottom container in a stack must not support more than five loaded containers superimposed thereon. For this reason the height of the container hold is limited to that necessary to receive stacks of six containers and container ships designed to take larger stacks of containers has not been built.

The object of this invention is to provide an apparatus for supporting upper containers than sixth container, which enables the container cell to store seven or more containers.

A preferred embodiment of this invention will now be described with reference to the accompanying drawings wherein:

FIG. 1 is a side view showing a container hold constructed in accordance with this invention;

FIG. 2 is a sectional view taken on line 2 2 in FIG. 1;

FIG. 3 is a perspective view of the supporting apparatus in accordance with this invention;

FIG. 4 is an enlarged plan view of the supporting apparatus;

FIG. 5 is a sectional view taken on line 5 5 in FIG. 4;

FIG. 6 is a sectional view taken on line 6 6 in FIG. 4;

FIG. 7 is a side view showing another embodiment of this invention;

FIG. 8 is a plan view of the apparatus shown in FIG. 7;

FIG. 9 is an enlarged plan view of the apparatus; and

FIG. 10 is a sectional view taken on line 10 10 in FIG. 9.

Referring to the drawing and more particularly to FIGS. 1 and 2, containers 11 above sixth containers are supported by removable supporting members 14 which are supported by structural member 13 extending the width of the container hold at top of sixth containers 12. As shown in FIGS. 3, 4, 5 and 6, the removable supporting member 14 comprises a pair of end plates 18 and side members 18a to form a frame. Each end plate 18 has projections 18b and 18c to be placed on the structural member 13 and a bracket 15 secured to the member 13. The end plate is also provided with a pair of blocks 16 for positioning a container thereon and lifting thereof. The blocks 16 are hanged to hooks of a container crane, so that the removable supporting member 14 can be inserted into a container cell formed by four container guides 17. The removable supporting member 14 is supported by the structural member 13 and bracket 15 at top of the sixth container and seventh and upper containers 1] are supported by the removable supporting member 14.

In the embodiment of FIGS. 7, 8, 9 and 10, the removable supporting member 14 extends over the several container cells. The removable supporting member 14 is supported by the structural member 13 and a shelf 20.

From the foregoing, in accordance with this invention, it is possible to design the large container ship into preferable and economical form without limitation of height of the container hold.

I claim:

1. A container ship having a hold with vertically disposed angular container guides defining guideways for directing vertical movement of containers during unloading and loading of the hold, supporting structures disposed alongside said angular guides outside of said guideways, said structures including horizontal structural members extending the width of the hold along the ends of said guideways at a height corresponding to the top of a sixth container in said guideway, a removable supporting member disposed horizontally within said guideway and having at least end portions thereof projecting endwise beyond said guideway to overlap said structural members and be supported thereby independently of said angular container guides.

2. A container ship according to claim 1 wherein said supporting structure includes brackets extending alongside said guides outside of said guideways and perpendicular to said structural members, and wherein further the end portions of said removable supporting member project sideways out of said guideway to overlap said brackets and to be additionally supported thereby.

3. A container ship according to claim I wherein said end portions comprise rectangular plates having the corner portions thereof cut out to accommodate said angular container guides.
